[Vm-beginners] aarch64 stack spur progress

[ken.dickey at whidbey.com]

Small progress.

I now have a squeak which runs spur format images on arm64 with only 64 bit
libs:

    sqstkspur64linuxht/lib/squeak/5.0-20181206231/*

This is a proof of concept, as I hacked several files to get here,
basically for null cases.

In particular, I have a custom "mvm" which sets opts
  -D__arm64__
  -D__ARM_ARCH_8A__
and 

  TARGET_ARCH="-march=armv8-a"

which are used in "sqUnixMain.c" and "sqUnixHeartbeat.c"

And of course I added a trivial case to config.guess

    aarch64:Linux:*:*)
    echo ${UNAME_MACHINE}-unknown-linux-gnu
    exit 0 ;;

This compiled and ran OK on LePotato (AML-S905X-CC) soc, tested with
Cuis5.0-3485.image.

Armbian:aarch64:~ >>> uname -a
 Linux spud 4.14.70-meson64 #269 SMP PREEMPT Wed Sep 19 11:21:29 CEST 2018
aarch64 GNU/Linux

How do I make this regular/harmless?  What testing? ...

I was thinking perhaps the "mvm" in

  oscogvm/build.linux64x64/squeak.stack.spur/buildARM64/

Thanks again,
